Pneumatic & Hydraulic Cylinders

Alkon Corporation is your partner in trusted performance , delivering the DuraLink ™ product family of high-quality pneumatic fittings for industrial and mobile applications. The DuraLink family also includes DOT tubing designed specifically for reliable performance in mobile equipment. Alkon DuraLink ™ Solution: Alkon DuraLink ™ DOT Tubing: Alkon DuraLink ™ DOT tubing is designed for dependable performance in air brake systems. Manufactured in the U.S., this tubing provides stability throughout the supply chain by eliminating long lead times and the unpredictability of imported materials. DuraLink™ tubing surpasses DOT FMVSS 49 CFR 571.106 and SAE J844 standards, with tensile strength and bend-test performance far exceeding competitive products. The Alkon DuraLink™ solution, combining our fittings and tubing, delivers a tensile peak load nearly 200% of the required standard. While optimized for Alkon’s DOT push-to-connect fittings, the tubing maintains trusted performance when paired with other manufacturers’ products. DuraLink™ tubing is available in multiple sizes and colors, with standard roll lengths and cut-to-length options that support both new builds and repair applications. Pneumatic Fittings: Built for durability and precision, Alkon fittings are manufactured and tested in North America for consistent quality, shorter lead times, and reliable, leak-free performance in the field. As a part of the Alkon DuraLink ™ product family, our fittings reflect our commitment to long-term reliability and trusted performance. Our DOT-compliant push-to-connect fittings meet and exceed SAE J2494-3 and FMVSS 49 CFR 571.106 standards. Engineered for rugged use, they provide secure, vibration-resistant connections and can handle tight bend radii. Available in brass, composite, and nickel-plated options, our fittings come in a wide range of sizes to suit your needs.
